(Korea double acting cylinder,produced by Hengyu Hydraulic Co., Ltd）

double acting cylinder are widely used in Korea，because of smooth movement，high work efficiency，long service life.So our company has designed double acting cylinder for customers from Korea.

Introduction to double acting cylinder:

double acting cylinder piston rod material introduction: In general, we use 45 steel to produce double acting cylinder piston rod. It has a large impact force when it is used, and some good performance steel are also used in the heavy load transmission. In order to have enough work intensity when using, and can ensure normal use, this is still more critical to have a detailed understanding of the material.

If it is found that the double acting cylinder lubrication is poor or the double acting cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the double acting cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the double acting cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the double acting cylinder center line. In this way, when the piston works in the double acting cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the double acting cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

The internal leakage of the double acting cylinder should be prevented when the double acting cylinder is used. The internal leakage of double acting cylinder includes the leakage caused by excessive wear of double acting cylinder block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.

double acting cylinders in series, parallel and series parallel. Series: In the double acting cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the double acting cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the double acting cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the double acting cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.

Answers to some questions about double acting cylinder:

Why can't the hydraulic cylinder be replaced with water?
Hydraulic oil for hydraulic transmission has a variety of requirements for viscosity, density, flow rate, and temperature, which are not available for water.

How to remove the air in hydraulic cylinder?
Connected the cylinder to the system, and reciprocating move with full stroke several times, then the air can be eliminated . There is also a clunky method as follows: first remove the rod cavity oil pipe, connect the rodless cavity oil circuit to extend all the cylinders, and then remove the rodless cavity oil pipe, connect the rod cavity oil pipe and withdraw all the cylinders, and then connect the rodless cavity oil pipe, so that there is no air in the cylinder.
